Is there any way to auto configure the Certificate Principal Name: to something other than the External Host Name: in the Outlook Anywhare settings? History: I just recently configured AutoDiscovery internally and externally and now the Outlook Anywhere settings are being set automatically. Problem is we are using a wild card certificate. Up until I configured Autodiscovery it was not an issue I changed the Certificate Principal Name: to msstd:*domain.com and everything worked well. Now every time the user opens Outlook 2007 & 2010 it changes the Certificate Principal Name: to msstd:exchange.domain.com. Is there any way short of buying new certificates or turning off autodiscovery to fix this? Regards, John

Hi, You don't say where you changed the Certificate Principal Name, but if you didn't configured the Outlookprovider EXPR, it explains why the users Outlook profiles gets set to msstd:exchange.domain.com automatically. Example: Set-OutlookProvider EXPR -CertPrincipalName msstd:*.domain.com Martina Miskovic

I was doing in manually in the Outlook setup.<o:p></o:p> This looks like exactly what I was looking for. I will test it and let you know if it resolve my problem.<o:p></o:p> This issue steams from another problem where internal users were randomly being prompted for logon redentials and everything led me to a autodiscovery configuration issue (I never configured any autodiscover DNS entries) When I did make the DNS entries external users started having the issues as mentioned earlier.<o:p></o:p> In some respect Exchange 2003 was a lot easier to manage.

Hi, By the way, is your internal domain name the same as your external domain name? With the cmdlet that Martina mentioned, it will set the certificate for Expr(outlook anywhere.) Please try to test the issue without outlook anywhere configured inside the network.Xiu Zhang TechNet Community Support

Yes. internal and external is the same. I find it easier that way. Thanks Martina that worked great.
